Here's something I threw together today to help track my LG progress in terms of speed/accuracy. I've classified each game using the Powerscore method, and added entries for multiple attempts for those of us who are using Pithypike's method of printing out 3 of each game and tracking your progress. You can make graphs/perform data analysis as necessary if you like. Not sure if this will be of any help to anyone, but I made it for myself and figured I might as well post it on here just in case.

It looks butchered on Google Docs, but if you download the file and open it in Excel it should work fine. Nothing flashy involving formulas or anything (because I don't know how to do that, but if any of you do and have suggestions to improve this they're much appreciated), but hopefully it'll help you track your LG improvement.
